Relation-theoretic metrical coincidence theorems under weak C-contractions and K-contractions
AIMS Mathematics, 2021 In this paper, we prove some coincidence point theorems for weak C-contractions and K-contractions involving a new auxiliary function in a metric space endowed with a locally f-transitive binary relation.

The extended permutohedron on a transitive binary relation [PDF]
, 2013 For a given transitive binary relation e on a set E, the transitive closures of open (i.e., co-transitive in e) sets, called the regular closed subsets, form an ortholattice Reg(e), the extended permutohedron on e.

Fixed Point Theorems for Nonexpansive Mappings under Binary Relations
Mathematics, 2021 In the present article, we establish relation-theoretic fixed point theorems in a Banach space, satisfying the Opial condition, using the R-Krasnoselskii sequence. We observe that graphical versions (Fixed Point Theory Appl.

Notes on Knaster-Tarski Theorem versus Monotone Nonexpansive Mappings
Moroccan Journal of Pure and Applied Analysis, 2018 The purpose of this note is to discuss the recent paper of Espínola and Wiśnicki about the fixed point theory of monotone nonexpansive mappings. In their work, it is claimed that most of the fixed point results of this class of mappings boil down to the ...

On (Λ,Υ,ℜ)-Contractions and Applications to Nonlinear Matrix Equations
Mathematics, 2019 In this paper, we study the behavior of Λ , Υ , ℜ -contraction mappings under the effect of comparison functions and an arbitrary binary relation. We establish related common fixed point theorems.

On the properties of contact binary stars
, 2004 A catalogue of light curve solutions of contact binary stars has been compiled. It contains the results of 159 light curve solutions. Properties of contact binary stars were studied by using the catalogue data. As it is well known since Lucy's (1968a,b)
